blocking the drain. Make a solution of warm
water with non-chloride detergent and pour
1/2 gallon (1.9 liters) of it down the compartment
drain. Rinse by pouring 1/2 gallon (1.9 liters) of
hot water down the compartment drain.
Figure 8: Oven Cavity
COMPARTMENT
The compartment, pan guides, and baffl e should
be cleaned daily. The exterior should be cleaned
daily.
Remove the pan guides by lifting up and out.
Wash with a solution of warm water with non-
chloride detergent. Rinse with warm water.
Remove the baffl e from the compartment by
lifting up and out. Wash with a solution of warm
water with non-chloride detergent. Rinse with
warm water.
NOTE: Failure to reinstall baffl e after cleaning
will aff ect cooking performance.
Wash the inside of the compartment with
a solution of warm water with non-chloride
detergent. Rinse with warm water.
Thoroughly clean the exposed surfaces (sides,
front, door and top) with a damp cloth and polish
with a clean cloth daily. To remove discolorations,
use a nonabrasive cleaner.
DOOR GASKET
Clean the gasket sealing surface of the
compartment door daily to remove food acids for
maximum gasket life. Do not use any solvents or
sharp instruments. Wash with a cloth moistened
in a solution of mild detergent and warm water.

STAINLESS STEEL EQUIPMENT CARE
AND CLEANING
Contrary to popular belief, stainless steels
ARE susceptible to rusting.
Corrosion on metals is everywhere. It is
recognized quickly on iron and steel as unsightly
yellow/orange rust. Such metals are called
“active” because they actively corrode in a
natural environment when their atoms combine
with oxygen to form rust.
Stainless steels are passive metals because
they contain other metals, like chromium,
nickel and manganese, that stabilize the atoms.
400 series stainless steels are called ferritic,
contain chromium, and are magnetic; 300 series
stainless steels are called austenitic, containing
chromium and nickel; and 200 series stainless,
also austenitic, contains manganese, nitrogen
and carbon. Austenitic types of stainless are
not magnetic, and generally provide greater
resistance to corrosion than ferritic types.
With 12 to 30% chromium, an invisible passive
lm covers the steel’s surface acting as a shield
against corrosion. As long as the lm is intact
and not broken or contaminated, the metal is
passive and stainless. If the passive lm of
stainless steel has been broken, equipment
starts to corrode and starts to rust.
Enemies of Stainless Steel
There are three basic things which can break
down stainless steel’s passivity layer and allow
corrosion to occur.
1. Mechanical abrasion.
2. Deposits and water.
3. Chlorides.
Mechanical abrasion means those things that
will scratch a steel surface. Steel pads, wire
brushes and scrapers are prime examples.
Water comes out of the faucet in varying degrees
of hardness. Depending on what part of the
country you live in, you may have hard or soft
water. Hard water may leave spots, and when
heated leaves deposits behind that if left to sit, will
break down the passive layer and rust stainless
steel. Other deposits from food preparation and
service must be properly removed.
Chlorides are found nearly everywhere. They
are in water, food and table salt. One of the worst
chloride perpetrators can come from household
and industrial cleaners.
So what does all this mean?
Don’t despair!
Here are a few steps that can help prevent
stainless steel rust.
1. Use the proper tools.
When cleaning stainless steel products, use
non-abrasive tools. Soft cloths and plastic
scouring pads will not harm steel’s passive
layer. Stainless steel pads also can be used
but the scrubbing motion must be in the
direction of the manufacturers’ polishing
marks.
2. Clean with the polish lines.
Some stainless steel comes with visible
polishing lines or grain. When visible lines
are present, always scrub in a motion parallel
to the lines. When the grain cannot be seen,
play it safe and use a soft cloth or plastic
scouring pad.
3. Use alkaline, alkaline chlorinated or non-
chloride containing cleaners.
While many traditional cleaners are loaded
with chlorides, the industry is providing
an ever-increasing choice of non-chloride
cleaners. If you are not sure of chloride
content in the cleaner used, contact your
cleaning supplier. If your present cleaner
contains chlorides, ask your supplier if
they have an alternative. Avoid cleaners
containing quaternary salts; it also can attack
stainless steel and cause pitting and rusting.
— 16 —
C24EO SERIES STEAMER
4. Treat your water.
Though this is not always practical,
softening hard water can do much to reduce
deposits. There are certain lters that can be
installed to remove distasteful and corrosive
elements. To insure proper water treatment,
call a treatment specialist.
5. Keep your food equipment clean.
Use alkaline, alkaline chlorinated or non-
chloride cleaners at recommended strength.
Clean frequently to avoid build-up of hard
stubborn stains. If you boil water in stainless
steel equipment, remember the single
most likely cause of damage is chlorides
in the water. Heating cleaners that contain
chlorides have a similar eff ect.
6. Rinse, rinse, rinse.
If chlorinated cleaners are used, rinse
and wipe equipment and supplies dry
immediately. The sooner you wipe off
standing water, especially when it contains
cleaning agents, the better. After wiping
equipment down, allow it to air dry; oxygen
helps maintain the stainless steel’s passivity
lm.
7. Never use hydrochloric acid (muriatic
acid) on stainless steel.
8. Regularly restore/passivate stainless
steel.

1. Stainless steels rust when passivity (fi lm-shield) breaks down as a result of scrapes, scratches,
deposits and chlorides.
2. Stainless steel rust starts with pits and cracks.
3. Use the proper tools. Do not use steel pads, wire brushes or scrapers to clean stainless steel.
4. Use non-chlorinated cleaners at recommended concentrations. Use only chloride-free cleaners.
5. Soften your water. Use fi lters and softeners whenever possible.
6. Wipe off cleaning agent(s) and standing water as soon as possible. Prolonged contact causes
eventual problems.

COOKING HINTS
The steamer effi ciently cooks vegetables and
other foods for immediate serving. Steam
cooking should be carefully time controlled.
Keep hot food holding-time to a minimum to
produce the most appetizing results. Prepare
small batches. Cook only enough to start serving,
then cook additional amounts to meet demand.
ACCEPTABLE PAN SIZES
The steamer accommodates combinations of full,
half and one-third size pans, solid or perforated.
Model Number of Pans Accommodated
Depth of Pan
1" 21/2"4" 6"
C24EO3 6321

COOKING GUIDELINES
The steamer cooks vegetables, frankfurters,
eggs in their shells, and certain other meats or
food items at atmospheric pressure.
These cooking guidelines are suggestions only.
You should experiment with your food products
to determine the cooking times that will give you
the best results. Variables which aff ect cooking
time include size, weight, thickness of foods,
temperature, density, previous condition of the
foods (fresh, pre-blanched or frozen) and degree
of doneness desired.
PREPARATION
Prepare vegetables, fruits, meats, seafood and
poultry normally by cleaning, separating, cutting,
removing stems, etc. Cook root vegetables in
a perforated pan. Other vegetables may be
cooked in a perforated pan unless juices are
being saved. Liquids can be collected in a solid
12" x 20" pan placed under a perforated pan.
Perforated pans are used for frankfurters,
wieners and similar items when juices do not
need to be preserved. Solid pans are good
for cooking puddings, rice, and hot breakfast
cereals. Vegetables and fruits are cooked in
solid pans in their own juice. Meats and poultry
are cooked in solid pans to preserve their juice
or retain broth.
Canned foods can be heated in their opened
cans (cans placed in 12" x 20" solid pans) or
the contents may be poured into solid pans.
DO NOT place unopened cans in the steamer.
Frozen Food Items
Separate frozen foods into smaller pieces to
allow more effi cient cooking.
Use a pan cover for precooked frozen dishes
that cannot be cooked in the covered containers
in which they are packed if they require more
than 15 minutes of cooking time. When a cover is
used, approximately one-third additional cooking
time is necessary.
Cooking time for frozen foods depends on the
amount of defrosting required. If time permits,
allow frozen foods to partially thaw overnight in
a refrigerator. This will reduce their cooking time.
